^^^^ This change hides the switch of the default for zypper dup: after
this update, zypper dup will default to –no-allow-vendor-change, which
has been the recommended way for Tumbleweed for a long time now.

NOTE: This will ONLY update your default configuration if you did not
touch /etc/zypp/zypp.conf – If you had local modifications, rpm will
have put a file NEXT to it (zypp.conf.rpmnew), in which case you have
to adjust the settings manually (or you likely already did)

Hope this will eliminate a good part of the issues people kept on
reporting about updates – bringing Tumbleweed one step closer to what
you expect it to do in all situations.
